Rolls Royce Under Scrutiny Ahead of UK Nuclear Reactor Decision

The UK is planning a big shift toward cleaner energy. Nuclear power is a key part of that plan. One of the top companies in this race is Rolls-Royce. Most people know Rolls-Royce for luxury cars, and the company also works in energy and defense. Now, it is developing compact nuclear reactors known as Small Modular Reactors, or SMRs.

These reactors are cheaper and faster to build than old nuclear plants. They could help the UK meet its Net Zero goals by 2050. But not everyone is cheering. As the government gets ready to decide who will build the next set of reactors, all eyes are on Rolls-Royce.

Some experts support their plan. Others are raising tough questions. Are these reactors safe? Are they worth the cost? And can Rolls-Royce deliver on time?

Let’s explore why Rolls-Royce is under pressure, what’s at stake, and what the future might hold for nuclear power in the UK.

Background on Rolls‑Royce’s Nuclear Ambitions

Rolls‑Royce is not new to nuclear power. They helped power UK submarines. Now they aim to build smaller, modular reactors. These SMRs produce about 470 MW each, enough to power around 1 million homes. They won a top spot among four bidders in a design competition.

They’ve invested over £280 million, with £210 million from the UK government. In July 2024, their design passed an important safety check, GDA Step 2, with no major issues flagged.

The UK Government’s Nuclear Strategy

The government aims to triple nuclear power by 2050 from around 6 GW to about 24 GW. This fits into a plan called Net Zero. It needs more clean, reliable power. SMRs are vital to this plan.

On June 10, the government pledged £11.5 billion for Sizewell C and £2.5 billion for SMRs. They hope SMRs speed up construction and stabilize electricity costs.

Why Rolls‑Royce Is Under Scrutiny

With big ambitions come big questions. Investors ask:

• Can Rolls‑Royce stay on time and under budget? SMRs are promise‑filled, but still unproven. Costs and build delays could hit hard.
• Are they really safe? Regulators cleared the design stage, but some worry about long‑term waste and site safety.
• Do they make financial sense? Environmental groups like Greenpeace say renewables may be cheaper and faster.

So, the big question is: can Rolls‑Royce deliver what’s promised?

Technical and Financial Hurdles

SMRs are promises on paper, but real plants are still years away. Their reactors may not run until the mid-2030s. That’s later than hoped. They must now complete GDA Step 3 and go through site licensing.

Factory‑built modules could speed up assembly. But building the factories costs money up front. Plus, each reactor still needs unique handling on-site.

Rolls‑Royce Share Price

Let’s break down the share story:

• Record high: RR shares climbed above 905 pence after news of the SMR win.
• Surge trend: They climbed over 700% in five years, hitting 817 % in early 2025.
• Analyst views: Citi thinks rolling out 16 SMRs could add 10–15 p per share.
• Valuation caution: The post-deal boost may already be priced in. Some tell us it’s a “hold” or “sell” time

Industry Reactions and Stakeholder Opinions

Energy experts are split. Some say SMRs could lead to a UK nuclear comeback. Citi analysts think Rolls‑Royce is the likely winner since it is UK‑based and has export power.

Politicians of all parties agree that nuclear power must grow. Labour’s Keir Starmer supports SMRs as part of a “golden age of nuclear power”. Environmentalists applaud the goals but warn SMRs must avoid large cost and time overruns.

Local communities are watching, too. They’ll want strong safety and waste plans before they host new sites.

What’s at Stake for the UK and Rolls‑Royce

If this works, Rolls‑Royce could bring about 3,000 jobs during construction. SMRs might power 3 million homes. That means cheaper energy and less carbon.

It could also give the UK a global edge. Firms from the US, Canada, and the Czech Republic are closely observing. Export contracts might follow.

But failure could hurt Britain’s nuclear push for years. Costs rising or delays would hit investor trust. Rolls‑Royce might lose key credibility.

Final Words

Rolls‑Royce’s SMR bid marks a new push for clean energy in Britain. Government funding and regulatory progress show hope. But many questions remain. Can they finish safely, affordably, and on time?

We’ll find out once contracts are signed and final decisions are made later this year. This decision may influence the future of UK energy for many years.
